Description

Technical Field

[0001] The utility model relates to the technical field of antifreeze powder spraying devices, and more specifically, to an antifreeze powder spraying device for trains in winter. Background Art

[0002] my country is a country with abundant coal resources and also a large coal consumer. Most of the coal is consumed in the form of thermal power generation, especially during the low temperatures in winter, when coal consumption is much greater than in other seasons. This places extremely high demands on the transportation capacity of coal. Currently, the main mode of transportation for large amounts of coal in China is freight trains. However, since freight train cars are not closed, some of the coal may freeze and form lumps in the low temperature environment during transportation, resulting in a certain degree of waste of coal resources.

[0003] When transporting clean coal in extremely low temperatures in winter, operators often use antifreeze powder to prevent the clean coal from agglomerating and sticking to the train wall due to the moisture inside the clean coal, thereby ensuring the normal transportation and loading and unloading of the clean coal. In the current actual transportation scenarios, the deployment of antifreeze powder is generally done manually, but manual powder spreading inevitably leads to uneven powder spreading, and working in extremely low temperature environments in winter also brings a considerable burden to operators, so it needs to be improved.

[0034] Among them, a No. 2 motor 13 is fixedly installed on the rear side of the right surface of the spray tower 1, and the other end of the output shaft of the No. 2 motor 13 is fixedly sleeved with a driving shaft 14, and the outer surface of the driving shaft 14 is fixedly sleeved with a driving gear 15, and the outer surface of the driving gear 15 is meshedly connected with a driven gear 12 located on the left side of the No. 2 discharge pipe 4, the inner surface of the driven gear 12 is fixedly sleeved with the outer surface of the No. 1 discharge pipe 3, the left surface of the driven gear 12 is movably connected to the right surface of the spray tower 1, and the right surface of the driven gear 12 is movably connected to the left end of the No. 2 discharge pipe 4.

[0035] When the second motor 13 is running, the driving shaft 14 will drive the driving gear 15 to start rotating. Due to the meshing of the outer surfaces of the driven gear 12 and the driving gear 15, the driven gear 12, the first discharge pipe 3 as a whole and the second discharge pipe 4 will all start rotating under the drive of the driving gear 15.

[0036] Among them, a feed barrel 27 is movably sleeved on the right side of the inner surface of the pipe sleeve 2, and a connecting plate 26 is fixedly connected to the outer surface of the bottom of the feed barrel 27. The outer surfaces of the left and right sides of the connecting plate 26 are fixedly connected to the inner surface of the spray tower 1. The right end of the feed barrel 27 is fixedly installed with a No. 4 motor 28 located inside the spray tower 1, and the other end of the output shaft of the No. 4 motor 28 is fixedly sleeved with a conveying shaft 29. The left end of the conveying shaft 29 passes through the feed barrel 27 and extends to the inside of the feed barrel 27. The outer surface of the conveying shaft 29 is fixedly connected with a conveying impeller 30 located inside the feed barrel 27.

[0037] When the No. 4 motor 28 is running, the conveying shaft 29 and the conveying impeller 30 will start to rotate, and the rotation of the conveying impeller 30 will push the antifreeze powder inside the feeding barrel 27 to move to the left and enter the No. 1 discharge pipe 3, and finally make the antifreeze powder spill out into the freight compartment through the powder nozzle 34.

[0038] Among them, sliding grooves 31 are opened on the front and back sides of the right surface of the spray tower 1, and the lower side of the inner surface of the sliding groove 31 is movably connected with a sliding block 32, and the right surface of the sliding block 32 is fixedly connected with a powder box 16, the left surface of the powder box 16 and the right surface of the spray tower 1 are movably connected, and the top of the right surface of the spray tower 1 is fixedly connected with a limit block 17 located above the feed port 33.

[0039] Due to the design of the sliding groove 31 , the powder box 16 as a whole can move up and down along the inner surface of the sliding groove 31 , and the limit block 17 plays a role in limiting the movement stroke of the powder box 16 .

[0040] Among them, a mounting frame 18 is fixedly connected to the left side of the upper surface of the spray tower 1, and a No. 3 motor 19 is fixedly installed on the left side of the top of the outer surface of the mounting frame 18. A round shaft 20 is fixedly sleeved on the other end of the output shaft of the No. 3 motor 19, and the rear end of the round shaft 20 passes through the mounting frame 18 and extends to the rear side of the mounting frame 18.

[0041] When the third motor 19 is running, the circular shaft 20 will start to rotate.

[0042] The outer surface of the circular shaft 20 is fixedly sleeved with a cable winding roll 21 located between the mounting frames 18 , the outer surface of the cable winding roll 21 is wound with a steel cable 22 , and the other end of the steel cable 22 is fixedly connected to the left side of the upper surface of the powder box 16 .

[0043] When the third motor 19 is running, the round shaft 20 will drive the cable winding reel 21 and the steel cable 22 to start rotating. At this time, the other end of the steel cable 22 will start pulling the powder box 16, so that the powder box 16 as a whole starts to move upward along the inner surface of the sliding groove 31.

[0044] Among them, the inner surface of the spray tower 1 is fixedly connected to a stacking bin 23 located below the feed port 33, and a pneumatic cylinder 24 is fixedly installed on the right side of the inner surface of the spray tower 1. The left end of the pneumatic cylinder 24 is fixedly connected to a closing plate 25 located between the stacking bin 23 and the connecting plate 26.

[0045] Due to the design of the pneumatic cylinder 24 , the closing plate 25 can play a role in blocking the bottom end of the material storage bin 23 .

[0046] The working principle and use process of this utility model:

[0047] First, the operator pours the antifreeze powder into the powder box 16 and then starts the No. 3 motor 19. As the No. 3 motor 19 runs, the round shaft 20 will drive the cable reel 21 and the steel cable 22 to start rotating. At this time, the other end of the steel cable 22 will pull the powder box 16 as a whole to start moving upward under the limit of the sliding groove 31. When the upper surface of the powder box 16 contacts the limit block 17, the antifreeze powder inside the powder box 16 will slide from the inside of the powder box 16 into the inside of the spray tower 1 due to the design of the powder box 16 and accumulate in the inside of the stacking bin 23.

[0048] When it is necessary to spray antifreeze powder, the operator starts the pneumatic cylinder 24 and the No. 4 motor 28. The operation of the pneumatic cylinder 24 will cause the closing plate 25 to move to the right and eventually break away from the contact with the bottom of the stacking bin 23. At this time, the blockage of the bottom of the stacking bin 23 by the pneumatic cylinder 24 is released, which allows the antifreeze powder inside the stacking bin 23 to slide into the inside of the feeding barrel 27. The operation of the No. 4 motor 28 will cause the conveying shaft 29 to drive the conveying impeller 30 to start rotating, and the rotation of the conveying impeller 30 will push the antifreeze powder inside the feeding barrel 27 to move to the left. These antifreeze powders will pass through the inside of the No. 1 discharge pipe 3 and the No. 2 discharge pipe 4 in turn and then be sprayed out from the powder nozzle 34 into the freight car.

[0049] At this time, the operator starts motor No. 1 7 and motor No. 2 13. The operation of motor No. 1 7 will cause the rotating shaft 8 to drive connecting rod No. 1 9 to start rotating, and the rotation of connecting rod No. 1 9 will drive connecting rod No. 2 10 to make connecting rod No. 2 10 start rotating. At the same time, the other end of connecting rod No. 2 10 will push the movable plate 5, so that the No. 2 discharge pipe 4 as a whole begins to move to the left under the limit of connecting strip 11, and the operation of motor No. 2 13 will cause the driving shaft 14 to drive the driving gear 15 to start rotating. Due to the meshing between the driven gear 12 and the driving gear 15, the driven gear 12 will drive the No. 1 discharge pipe 3 and the No. 2 discharge pipe 4 to start rotating as a whole, so that the direction of the powder nozzle 34 changes. Finally, under the joint action of the No. 1 discharge pipe 3, the No. 2 discharge pipe 4 and the powder nozzle 34, the antifreeze powder is evenly sprayed inside the freight car, completing the spraying of antifreeze powder on the train.
